| description | A multi-mode switching hammer drill tool includes a casing, a drilling component and a hammering component matched with the casing, a shifting component, and a driving motor. The drilling component and the hammering component are cooperated with a driving motor for transmission through a transmission mechanism. The transmission mechanism includes a transmission member, a nested gear set, a drilling driven gear and a hammering driven gear. The lower bottom face of the hammering driven gear is higher than the upper top face of the drilling driven gear, the distance between the lower bottom faceof the hammering driven gear and the upper top face of the drilling driven gear is smaller than the tooth width of an outer covering gear, and the distance between the hammering driven gear and the drilling driven gear is smaller than the addendum circle diameter of the outer covering gear. The shifting assembly is controlled to drive the transmission part to shift the outer covering gear to slideup and down on a transmis |
